To all whom it may concern Be it known that I, AnoLrHUs D. GoonwiN, acitizen of the United States, residing at Lynchburg, in the county ofCampbell and State of Virginia, have invented certain new and usefulImprovements in Knife- Sharpeners; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it apper--;

provide a knife sharpener of this character having pivotally mountedjaws carrying the said files and adapted also to be adjusted toward andfrom each other to provide a relative lateral bodily adjustment as wellas a pivotal angular adjustment.

With these and other objects in view the invention consists in theconstruction and' novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing Figure 1 is a side elevation of a knife sharpenerconstructed in accordance with this invention, Fig. 2 is a frontelevation of the same, Fig. 8 is a horizontal sectional view on the line3-8 of Fig. 2, Fig. 4 is a horizontal sectional view on the line 44 ofFig. 2, Fig. 5 is a detail view illustrating the manner of connectingthe upper portions of the bars of the double jaw.

Like numerals of reference designate corresponding parts in the severalfigures of the drawing.

In the accompanying drawing in which is illustrated the preferredembodiment of the invention, 1 designates a base bolted or otherwisesecured to a bench 2 or other supporting surface and provided at thefront or outer end with a vertical flange 3 from which extends ahorizontal bolt 4. The base and the flange may be of any desired construction and the brace 5 may be employed if desired for supporting theflange 3. Mounted upon the horizontal bolt 4 are relatively adjustablejaws 5 and 6 which are secured in their adjustment by a thumb nut '7.The jaw 5 is a double jaw and is composed of spaced bars which havetheir lower ends fitted against the side faces of the jaw (3 whichconsist of a single bar arranged to operate at the interval or spacebetween the bars of the double jaw. The bars have lower enlargedportions 8 forming shoulders and provided with sockets 9 extendinginwardly from the shoulder 10 of each enlarged portion and adapted toreceive the end of afile.

The enlarged end of the bars of the double jaw are provided with alinedperforations 11 and the lower enlarged portion of the bar of the singlejaw is provided with a transverse slot 12. The screw passes through theperforations l1 and the slot 12 and the latter permits a relative bodilyadjustment in addition to the pivotal adjustment afforded by the bolt 4.lhe jaws 5 and 6 are equipped with files 13 and 14, a pair of files 13being mounted on the bars of the double jaw and a single file 14 beingcarried by the single jaw and arranged the reverse of the files of thedouble jaw. The files 13 have their shanks or tangs 16 arranged in thesockets of the shoulders 10 of their enlarged portions and the file 14has its shank or tang 17 at the top.

Each of the bars is equipped with a file rest 18 consisting of anL-shaped piece of metal secured at one of its sides or wings to the barand having its other side or wing extending from the inner face of thebar and provided with a tapering notch 19 which forms a seat for thethree cornered file and the latter is retained in its seat by a clamp 20consisting of a plate secured by a bolt or other suitable fasteningdevice 21 to the bar and provided with a projecting angularly disposedtongue 22 which engages the adjacent end of the file. The clamp iscurved transversely to present a concaved inner face to the file forsecurely holding the same in the rest. The bars of the double aw areconnected at their upper portions by a strap or plate'23 which maintainsthe upper portions of the bars in proper spaced relation. The lowerportions of the bars are adapted to clamp the lower portion of thesingle aw which is securely held in its adjustment. The jaws are adaptedto be arranged at different angles or inclinations and in the operationof the device a knife blade 24 is placed between the jaws and is drawnoutwardly. .The files are adapted to be changed until their abradingsurfaces are worn and and they may then be replaced by new files. WVhilethree cornered files are preferable other forms of abrading members mayof course be employed.

What is claimed is l. A knife sharpener of the class described includingjaws consisting of angularly related bars pivotally connected at one endand provided each adjacent to one of its ends with relatively fixed filereceiving means, files extending longitudinally of the said bars andeach having one end engaged in said means and clamps mounted on the barsat the other ends thereof for engaging the adjacent ends of the saidfiles.

2. Aknife sharpener of the class described including jaws arranged at anangle Copies of this patent maybe obtained. for five cents each, byaddressing the Commissioner of Patents,

and consisting of bars or members provided on the jaws and consisting ofplates arranged to engage the files for retaining'the same in the seats.V

A. A knife sharpener of the class described including jaws havingsockets each adapted to receive one end of a file, file rests providedwith flanges having notches forming file receiving seats and clampsconsisting of transverselycurved plates secured to the jaws and havingprojecting tongues arranged to engage the ends of the files,

In testimony whereof I mysignature in presence of two witnesses.
